Why don't I look like I'm losing weight?

ok so I've always been overweight my whole life so far. around janurary I started workout eating right and I have lost over 30 lbs now when I look in the mirror I still see that fat girl I didn't like. people say I look smaller and I don't see it. my clothes don't fit there too big and my measurements are getting smaller but I don't see it in the mirror. MY GOAL IS TO LOSE 80 LBS but I haven't reach that yet. but anyway how come I don't see it?
